94 740 IL - Hard Starting...now won't start

[bosox406]

My 1994 BMW 740 IL (93-94, E32 model) won't start. This slowly was starting with the symptoms of taking longer and longer to crank over. I changed the spark plugs and even change all the ignition coils. It will crank, but not turn over. In the past, when it would eventually start it ran fine. It just started taking longer and longer to turn over until now where it will not start. When it was running I ran a can of BG44K through on a tank of gas. It would run fine once going. Any ideas I can check myself before unloading my checkbook at the repair shop?

By any chance did you check to see if the fuel pump is working? thats a somewhat common cause of a no start.

Don't forget the fuel filter. Not only a cause of hard/no start but also will kill your fuel pump.

No, not yet. Someone else mentioned the Fuel Pump Relay at the DME. I will check. Thanks for the tip.

I just changed the fuel filter. Thanks for the tip
